In fact I do not have a big idea about http protocol neither about http
over udp cases. But I see this request in the standard protocol TR-069
cwmp (Amendment 5) and in this standard they require to send HTTP
messages over UDP and they are not asking to expect answer from the server.
Ref of TR-069:
(Annex M)

You are right for the 2 patches issue. I will send you 2 separate
patches for that. For the DISABLE_RECEIVE, I used it because for my case
I really do not care if the server answer to my UDP message or not, So
that's wy I want to disable the receive part in the process.

For the documentation I can send you documentation with the next patch.
please provide to me a template of your documentation. For the tests, I
made test for my case and it works properly but for the libcurl test
cases, I really do not have idea neither exeprience with that

CURLOPT_FORCE_UDP sound good. It was the first name I choosed ;-)
